I. INTRODUCTION

The Default-To-Manual-Restart (DTMR) Control is intended to reduce the possibility of “operator errors” that can result in DRY FIRING a fryer causing shortening to be scorched, heat mechanism damage, and/or a vat fire. A. SAFETY - The DTMR operates on 120 volt single phase electrical power, and like other electrical equipment, should not be operated with wet hands or while standing in water. Water should NEVER be sprayed on or at the DTMR, as there is a danger of electrical shock and / or serious damage to its electrical circuitry. Should the DTMR accidentally be sprayed with water, 1) IMMEDIATELY turn the Power OFF at the Main Power Switch and 2) IMMEDIATELY contact a qualified service agent to check the DTMR. The DTMR is located in close proximity to hot liquid shortening and care must be taken to avoid serious burns. The floor in front of, and area around the fryer should be kept clean and dry. Whenever anything is put into a cooking vat, care should be taken to not splash the hot shortening. Products should always be “placed” into the shortening, not thrown.

B. SAFE CLEANING PROCEDURE - Before performing any cleaning routine, electrical power to the DTMR should be turned OFF at the Main Power Switch. A SLIGHTLY dampened cloth may then be used to clean any debris from the face of the DTMR. DO NOT USE any cleaner or de-greaser solvent as they may mar the face or damage the internal circuitry of the control. Any questions regarding cor- rect cleaning procedures should be directed to the Customer Service Department at 1-800-525-8130.

II. DEFAULT-TO-MANUAL-RESTART CONTROL

A. GENERAL The Default-to-Manual-Restart (DTMR) Control along with an Electronic Thermostat is connected to a fryer’s electrical system to control operation of the fryer. The DTMR contains a Default-to-Off circuit that will DISABLE the fryer anytime the Drain Valve is OPEN, and a Default-to-Melt circuit that will automatically place the fryer in a SHORTENING MELT MODE to gradually and safely heat shortening each time the fryer’s Toggle ON/OFF Switch is turned ON.

NOTE: Some older stores may be equipped with a Fenwal Temperature Control in lieu of an Electric Thermostat.

B. ELECTRONIC THERMOSTAT The Electronic Thermostat has a temperature range from 200ºF (93ºC) to 400ºF (204ºC) and will accurately maintain a pre-set shortening cook temperature within ± 2º of the pre-set temperature.

C. DEFAULT-TO-MANUAL-RESTART CONTROL PANEL 1. BLUE READY TO START LAMP - When lit indicates the fryer’s Toggle ON/OFF switch is in the ON position, the Drain Valve is CLOSED and the fryer is ready to be placed in operation.

2. START BUTTON - When the button is momentarily pressed, it places the fryer in operation.

3. RED STARTED LAMP - When lit indicates the START BUTTON has been pressed, placing the fryer in operation.

4. AMBER MELT MODE LAMP - When lit indicates the fryer is in the MELT MODE and that the timer in the DTMR Default-to-Melt circuit is turning the fryer’s heat mechanism ON and OFF, as follows, to gradually and safely heat the shortening.

5. EXIT MELT BUTTON - When this button is momentarily pressed, the TIMER in the DTMR’s Default-to-Melt circuit will switch to the FULL-ON position allowing the Electronic Thermostat to heat shortening to its PRE-SET temperature.

ELECTRONIC THERMOSTAT CALIBRATION



PN 30A066 rev Jan2007 10

V Electronic Thermostat CALIBRATION - The Electronic Thermostat in all fryer configurations are equipped with a Dial and Knob and should be checked and calibrated when necessary as follows:

A. ENSURE electrical power and, if applicable, gas to the fryer has been turned OFF.

B. CAREFULLY drain sufficient shortening from the fryer to LOWER the shortening about 4” (102 mm) beneath the Electronic Thermostat sensing probe.

C. After the sensing probe has COOLED, loop the bead of an ACCURATE digital test thermometer temperature probe around the sensing element; then connect the probe to the thermometer.

D. Replace shortening drained in step B and ENSURE it is level with the shortening level mark on the rear of the vat; then turn the power and, if applicable, gas to the fryer ON.

E. Set the KNOB of the Electronic Thermostat to the CENTER (300) of the dial and periodically STIR the shortening in a COUNTER-CLOCKWISE (CCW) direction with a long handle skimmer to pull congealed shortening UPWARD from the Cold Zone area. F. When shortening has reached the set temperature and the RED indicator lamp on the fryer has turned OFF, allow the Electronic Thermostat to cycle ON and OFF about five (5) times to stablize the system.

G. After the shortening temperature has stablized, record the temperature reading of the TEST THERMOMETER immediately after the RED indicator lamp and the fryer turns OFF.

H. CAREFULLY loosen the set screw on the Electronic Thermostat KNOB without turning the thermostat potentiometer, set the thermostat knob pointer to the temperature recorded by the test thermometer; then tighten the set screw on the thermostat knob taking care not to turn the thermostat’s potentiometer.

I. Repeat steps A and B above, remove the test thermometer temperature probe from the Electronic Thermostat sensing element; then repeat step D to return the fryer to normal operation.
